Lafarge Canada launches low-carbon fuel facility at Exshaw plant
04 October 2024Canada: Lafarge Canada, a subsidiary of Holcim, has inaugurated a new low-carbon fuel facility at its Exshaw cement plant, in a joint effort with Geocycle Canada. The US$28m facility is supported by a US$7.4m contribution from Emissions Reduction Alberta through the government’s Technology Innovation and Emissions Reduction fund. It will reduce natural gas consumption by up to 50% for one of the plant’s kilns by substituting it with alternative fuels (AF) sourced from construction and demolition materials, primarily wood. Geocycle will process the materials into AF. This initiative is expected to divert up to 120,000t/yr of discarded materials from landfill, reducing CO₂ emissions by approximately 30,000t/yr.
President and CEO of Lafarge Canada (West), Brad Kohl, said "Our commitment to building a sustainable future is at the core of everything we do. The low-carbon fuel project is a prime example of how innovation and collaboration can drive positive change, lowering our environmental footprint through the use of discarded biomass materials while closing the material loop to conserve natural resources.”

Brazil: Votorantim Cimentos has inaugurated its first unit in Brazil for Viter, its agricultural inputs business, and Verdera, its sustainable waste management business. Located in Itaperuçu, the unit comprises a new Verdera waste crushing plant and an agricultural limestone production line for Viter. This initiative is part of a US$785m investment programme.
Verdera's Itaperuçu facility has a capacity of 48,000t/yr, tripling its previous capability, and is equipped with technology for sustainable waste treatment. The waste processed at the plant will be converted into clean energy for cement production at Votorantim's plant in Rio Branco do Sul, using co-processing technology developed by Votorantim in Brazil in 1991. Viter's new line will increase agricultural limestone production in Paraná. The Itaperuçu plant, along with the existing Rio Branco do Sul unit, brings Viter's total capacity to 1.5Mt/yr of agricultural limestone in Paraná. The new plant features filters for emission control and utilises biomass as a renewable energy source.
Saraburi cement plants to turn waste into energy
08 April 2024Thailand: Saraburi, which houses Thailand’s key cement plants, is expected to start converting waste to energy in a project led by the Thai Cement Manufacturers Association (TCMA). TCMA has developed a pilot project to create ‘ignitable waste pallets’, which will replace imported coal in cement production, according to TCMA chair Dr Chana Poomee. The process involves using waste from mining, cement plants and local communities to produce fuel, focusing on waste that cannot be reused or recycled.
Seven cement plants are located in the Tan Diao subdistrict due to its proximity to limestone mountains essential for cement production. The province is facing a growing waste management problem, owing to urbanisation and the expansion of agribusiness in the area. ‘Saraburi Sandbox’ project, a public-private-people partnership (PPP), seeks to address these issues.
Kittipong Promwong, president of the National Higher Education, Science, Research and Innovation Office, believes the Saraburi Sandbox is crucial to the government's commitment to lowering CO₂ emissions.
